Abstract

pá de rotor de instalação de energia eólica, uso de reforços de uma configuração em forma de onda, instalação de energia eólica, e, método para a produção de uma pá de rotor de instalações de energia eólica. a invenção se refere a uma pá de rotor de instalação de energia eólica. a pá de rotor tem uma raiz de pá de rotor (131), uma ponta de pá de rotor (132), uma aresta dianteira de pá de rotor (133) e uma aresta traseira de pá de rotor (134). a pá de rotor tem ainda um lado de pressão (136) e um lado de sucção (135), bem como pelo menos um reforço (200) pelo menos parcialmente entre o lado de sucção e o lado de pressão (135, 136). a pá de rotor tem uma direção longitudinal entre a raiz de pá de rotor (131) e a ponta de pá de rotor (132). o reforço (200) é de uma configuração em forma de onda na direção longitudinal da pá de rotor.wind power installation rotor blade, use of reinforcements from a waveform configuration, wind power installation, and method for producing a wind power installation rotor blade. The invention relates to a wind power installation rotor blade. the rotor blade has a rotor blade root (131), a rotor blade tip (132), a rotor blade front edge (133) and a rotor blade rear edge (134). the rotor blade further has a pressure side (136) and a suction side (135), as well as at least one reinforcement (200) at least partially between the suction side and the pressure side (135, 136). The rotor blade has a longitudinal direction between the rotor blade root (131) and the rotor blade tip (132). The reinforcement 200 is of a waveform configuration in the longitudinal direction of the rotor blade.
